Parents of children with Autism Spectrum Disorder (ASD) experience greater stress and caregiver burden than parents of children with other disabilities. To cope with the stress of long-term caregiving, they rely on professionals for support and guidance. However, parents continue to report unmet communication and support needs. To inform tailored communication for parents of a child with ASD, this study used the existing Family Caregiver Communication Typology framework which identifies four caregiver communication types (manager, carrier, partner, and lone) and their unique communication and support needs. In-depth, structured interviews were conducted with parents (n = 22) and ASD professionals (n = 28) to explore communication characteristics of ASD parent caregivers. A thematic analysis revealed communication behaviors among four ASD parent caregiver types, further validating the typology. Future research is needed to develop targeted interventions for improving family-centered care based on ASD parent caregiver types.
